My improvements relate particularly to.

latches for basement windows which are usually hinged to the upper portion of the window frame and are designed to swing inwardly, and the object of theinventionis to construct a latch or hook which will automatically catch the window to hold itopen and which can be automatically released by merely lifting the window.

The invention consists of that certain novel construction of latch which, when pivoted to hang vertically, will present a horizontal holding surface for the window sash, with an upper and a lower cam surface which upon raising the window will swing the latch to allow the edge of the sash to be engagedby'the horizontal surface, and upon av still further upper movement will again swing the latch o to release the window.

'In the drawings Figure l is a sectionalside elevation illustrating the latch in use. p Figure 2 is a similar view showing by dotted lines the action of the latch in releasing the window.

The basement window is shown at 1 hinged at 2 to the upper cross bar 3 of the window frame 4, so asto swing inwardly. Pivoted on a stud 5 on the plate 6 fastened to the suitable material, is stamped or out with a diagonal lower 'cam surface 9, terminating at the edge of-a V-shaped notch of sufficient The lower edge 10 of this notch is cut so as to lie horizontally when the latch is suspended so as to hang virtually by its own weight,j

r depth to receive the edge of the window sash. v

the sash the frameis lifted slightly, bringing the frame into contact with the upper cam 7 surface 12 which swings the'latch as indicat-' ed in Figure 2, thus releasing. the sash.

- It will be understoodthat the construction I-have shown for suspending the latch is only I f the preferredconstruction, and that the latch" may be suspended .in the proper position for" engagement with the edge of the sash in any convenient way. If the latch is'used with a wooden sash, I'may attach a metal plate to the sash which will compensate for the difference in thickness between a wooden and a metalsash. The latchmust be pivoted to swing readily when in operative position, and must'be of sufficient weight to hang in vertical position, 7 g Having thus described my invention, what I claim as-new and desireto secure by Let 1.

The'result of this construction is that when the latch issuspended in the pathway of the sash frame, upon lifting the sash, the edge dow is caught andirests upon the horizontal surface 10 of the notched-portion. To release
